A moving average is a technical analysis indicator that is used to smooth out price fluctuations in a stock or other financial asset. There are two main types of moving averages: simple moving averages (SMAs) and exponential moving averages (EMAs). In this article, we will discuss what these two types of moving averages are, how they are calculated, and how they can be used to analyze stocks.
Simple Moving Average (SMA)
A simple moving average is calculated by taking the sum of the closing prices of a stock over a certain number of periods and then dividing that sum by the number of periods. For example, if you want to calculate a 20-day SMA, you would take the sum of the closing prices of the stock over the past 20 days and divide that sum by 20. The result is the simple moving average for that stock.
SMAs are called “simple” because they use a straightforward mathematical calculation to determine the average price. They are often used to smooth out short-term price fluctuations and to identify longer-term trends in a stock’s price.
Exponential Moving Average (EMA)
An exponential moving average is similar to a simple moving average, but it gives more weight to recent price data. This means that an EMA will respond more quickly to price changes than a SMA.
To calculate an EMA, you first need to determine the weighting multiplier. This is typically set at a value between 0 and 1. The weighting multiplier is then applied to the most recent price data, with the most recent data receiving the highest weight. The resulting average is then plotted on a chart to show the stock’s price over time.
Using Moving Averages to Analyze Stocks

Moving averages can be used in a variety of ways to analyze stocks. Here are a few common techniques:
- Trend identification: By plotting a moving average on a chart, you can see the overall direction of a stock’s price. If the stock’s price is consistently above the moving average, it may be in an uptrend. If the stock’s price is consistently below the moving average, it may be in a downtrend.
- Support and resistance: A moving average can also act as a support or resistance level for a stock. If the stock’s price is approaching a moving average and then bounces off of it, it may be acting as a support level. If the stock’s price breaks through a moving average, it may be acting as a resistance level.
- Crossover signals: When two different moving averages cross over each other on a chart, it can be a signal that the stock’s trend is changing. For example, if a shorter-term moving average crosses above a longer-term moving average, it may be a bullish signal.
Keep in mind that moving averages should be used in conjunction with other technical analysis indicators and fundamental analysis to get a complete picture of a stock’s performance. They are not a standalone tool for making investment decisions.
